Abstract

In order to minimize the risk of infection when a large number of animals are injected with the same needle, the injecting gun is provided with a stainless steel sleeve which surrounds the needle. The sleeve comprises a first tube attached to the needle connecting body and a second tube telescopically slidable within the first tube against a spring. A detachable plastics cap incorporating a sterilizing substance is fitted on the free end of the second tube. In use of the gun to inject an animal, the cap is applied to the proposed site of injection and pressure is applied to the gun to cause the tubes to telescope, so that the point of the needle passes through the sterilizing substance and punctures the skin of the animal. On releasing the applied pressure, the point of the needle will be withdrawn from the animal and will pass back through the sterilizing substance under the action of the spring.
